Specification of Letters Intent.

Patented Nov. 16, 1909.

Application filed August 31, 1909. Serial No. 515,507.

- To all whom it may concern:

Be it known that I, WALTHER FELD, a subject of the King of Prussia and the German Emperor, of- Honningen-on-the-Rhine, in

the Kingdom of Prussia and German Empire, have invented new and useful Improvements in Gas-Washers, of which the following is a specification.

This invention has for its object to provide an improved gas washer of the general character described in my U. S. Patent No.

829,261, granted August 21, 1906.

The apparatus, according to the present invention, consists of, or comprises, a vessel,

or vessels, for the liquid, in the bottom of which vessel, or of each of which vessels, are openings for the passage of the gas, or vapor, and in the said vessel, or each of the said vessels, is a rotatable device analogous to that of the said former-patent, consisting of concentric funnels, or pipes, with,or with- I out, superposed plates, the said funnels or pipes, dippin into the, liquid in the vessel, and the said evice extending above the said liquid, so that, on rotation, the funnels, or

ipes, will, under centrifugal action, take up the liquid between them, and the device Wlll distribute it in the form of spray across the whole of the space through which the gases, or vapors, pass, so that the gases, or vapors, pass through sprayed liquid. The sprayed liquid returns into the vessel, or vessels, so that it circulates in the apparatus and a rotatable screen, with. a number of passages through it, formed, for example, of

strips, or slats, or of wire-work, or two, or more, such screens is, or are, provided above, or around, or both above and around, the device, or each device, or the topmost of the devices, for the purposes of separating moisture which the gases, or vapors, may

have taken up from the sprayed liquid.

In order that this invention, and how it may be performed, may be well understood, I will describe, with reference to the accompanying drawings, constructions in accordance therewith.

Figure 1 is a vertical section of a construction of the ap aratus, Fig. 2isaverti'cal section of the mid part of a modification, Fig. 3 is a half cross-section of one of the vessels showing the gas passages, and Figs. 4, 5 and 6 are vertical diagrammatic sections illustrating modifications as hereinafter described. w

Referring first to the construction shown in Fig. 1, the apparatus consists of vessels 6, one above the other, each for holding the liquid. The bottoms of the said vessels '6 are provided with gas passages g, which pas- Y sages g also serve as overflows for the liquid, although special overflows may be provided if desirable. Passingjdown the center of the apparatus is a rotatable shaft d which may be driven in any suitable way, such as by gearing as shown. Secured to this shaft are concentric funnels, or pipes, c, which may each carry at top an annular plate a, as shown in the lower vessel, or be without such plate, as shown in the upper vessel. The said funnels, or pipes, 0 at their lower ends dip into the liquid in the vessels e, and are arranged concentrically, so that there are spaces between them for the passage of liquid up between the said funnels, or pipes, c

and onto, and off from, the said annular plates a (when such plates are used), the said passage of liquid being induced by centrifugal action due to the motion of rotation given to the said funnels, or. pipes, 0, and annular plates (1 (when such plates are used) when the shaft d is rotated, the liquid bein under such centrifugal action, thrown o from the said upper ends of the funnels, or pipes, c, or from the annular plates a, so as to form a fine spray of the said liquid throughout the cross-sectional area of the space between the upper edges of the said funnels, or pipes, c, or the outer edges of the plates a, and the interior of the vessels e. The gases, or vapors, enter from below at f and pass up, through the gas passages g, and up through the aforesaid spacesin which the liquid is sprayed, as aforesaid, where the said gases, or vapors, are very thoroughly subjected to the action of the sprayed liquid,

passing, as they do, through sprayed liquid only. After the said gases, or vapors, pass from the uppermost division of the appara* tus, they pass through a perforated, or reticulated, rotating screen, or screens, h (two horizontal screens are shown in Fi 1) which is, or are, arranged horizontally %or, if preferred, conically) inside the upper part ofthe apparatus so that the gases, or vapors, are compelled to pass through the said screen, or screens, h, and thence to the outlet, the said screen, or screens, h separating any liquid-Which may be carried up with the gases, or vapors. The screen, or screens, h is, or are, secured to the shaft d. The liquid can the same letters .0

betadmitted to the upper vesel through any suitable inlet (such as that shown at m, for

example, which .may lead the liquor upon the middle of the uppermost screen la) and pass off through an outlet at the lower part of the I have also shown a vertical screen 12. inFig. 1, this being carried by arms secured to the shafts It may be used, or not.

The construction of the apparatus shown inFig. 2 is generally like that shown in Fig. 1, and correspondin parts are marked with reference, but I have shown in Fig. 2 a larger number'of vessels, and Iuhave shown in the two upper vessels rated, or reticulated, screens as being carried by the funnels '0, at topthereof, which combines the action of the plate a with the screen h. r v In Flg. 4 a vertical rotating perforated, or reticulated, screen, or, screens, It, is, or are,

used, arranged concentrically to the funnels,

or pipes, 0, the said screen, or screens, being carried by a top plate secured to the shaft d.

, The gases, or va ors, are compelled to pass,

with the spraye liquor, through the space between the funnels and screen, or screens, and thence through the screen, or screens. In the lower vessel e simple funnels, or

pipes, are shown, in the middle vessel'they have plates won them, and in the upper vessel the spraying device is .a combination the screens.

of conical funnels, or pipes, c curving. into annular plates a; The screens 72. may consist of one perforated, or reticulated, sheet, or of two, or more, such sheets, and the perforations, or reticulations, may be arranged so,

that those in one sheet are out of line with those in the other, or others, so as to compel the gases, or vapors, and liquid to repeatedly change their course when passing through forced through the screens together with the gas, or vapor. The gas passages g are arranged in the middle of the vessel, or vessels, 6 and servealso as overflows for the liquid.

The top plates, by which the vertical screens are secured to the arms connected with the shaft cl, have openings at their middle around the shaft and a short distance beneath each such opening is a a plate a which may }be of any suitable shape,

" such as horizontal, as in the lower vessel,

Zconical, as in the middle vessel, or con sist of two oppositely placed conical plates with asp'ace'between their edges, as 7 shown in Fig. 4, except that the rotatable screens It are made of a number of circular inclined slats secured together and to a top plate fixed to the shaft (1, and arranged after the manner of louvres, so that the liquid is given, by these slats, further centrifugal. impulse and'is again sprayed off from the. upper edges of the said slats. There may be, if desired, ,two,-or more, of these arrangements of slats so that the liquid passes from one to the other. 7

In all the figures the. course of the ases is shown by dotted line arrows an the course of the liquid is shown by solid line arrows.

Instead of the gases, j or vapors, being passed upward through-the apparatus, they may be passed downward therethrough, in

which case the inlet for the gases, or vapors, will be at the upper part of the apparatus, and the outlet for the gases, or vapors, will be at the lower part of the apparatus, and a rotating screen, or screens, of

either of the characters shown, will be placed inside the lower vessel 6. I 1

The apparatus enables a constant circulation of the liquid to be maintained. Surplus liquid which may be run in at thetop of the apparatus, or which may condense from'the gases, or vapors, can leave, or bedrawn from,

I the apparatus by a sealed outlet, or valve, at

bottom. 7

.There may be any suitable number of the vessels spraying devices and screens, as described, and the a paratus can be conveniently made up of sections, each carrying such an arrangement, and superposed and luted together, as illustrated. The vessel, or vessels, may be of any suitable form, for example they may be conical if desired.-

' I claim 1. In a gas washer a vessel adapted to contain the washing fluid, a rotatable shaft passing vertically therethrough, centrifugal members carried thereby and dipping their lower ends into said liquid and formed to spray'the latter by centrifugal action upon the rotation 'of the shaft, together with a screen rotating with said shaft, in combina' tion with a gas inlet and a gas outlet arranged -to direct' the gas I from the inlet through the sprayed liquid and screens to p the outlet,.substantially as described.-

2. In a gas washer a vessel adapted to con tain the washing fluid, a rotatable shaft passing vertically therethrough, centrifugal members carriedthereby and dipping their lower ends into said liquid and formed to spray the latter by centrifugal action upon the rotation of the shaft, together with a vertical screen rotating with said shaft, in combination with a gas inlet and a gas out let arranged to direct the gas from the inlet through the sprayed liquid and screens to outlet arranged to direct the gas from the inlet through the sprayed liquid and screens to the outlet, substantially as described.

4. In a gas washer, a vessel adapted to contain the washing fluid, a rotatable shaft passing vertically therethrough, centrifu galv members carried thereby and dipping their lower ends into said liquid and formed to spray the latter by centrifugal action upon the rotation of the shaft, together with a screen rotating with said centrifugal members and arranged to supplement the centrifugal action of the latter, in combination with a gas inlet and a gas outlet arranged todirect the gas from the inlet through the sprayed liquid and screens to the outlet, substantially as described. I
